| titleOfInvention | Polymerisation method |
| abstract | A method of controlling molecular weight of acrylate type liquid crystal polymers during polymerisation where the appropriate monomer is dissolved in a suitable solvent followed by addition of an initiator and heating of the mixture. Control of the molecular weight is achieved by use of appropriate concentration of monomer in the solvent. Typically, initiators such as AIBN and benzoyl peroxide can be used with solvents such as dichloroethane, dichloromethane, dimethylsulphoxide and toluene. A calibration chart can be constructed of degree of polymerisation against concentration of monomer in the solvent, with the result that for a given desired degree of polymerisation of an acrylate type liquid crystal polymer the corresponding required concentration of monomer in solvent can be determined. |
